Algorithm time complexity 1- what is it

In these days, we have super fast computers that can compute so fast we can’t even imagine it. So should we care about our algorithm time coplexity?

Well I hope that with little bit of math and some examples I will convince you that you should care.

How to compute time complexity?

At first you have to know what can influence the performance of your algorithm.
– Hardware (sigle vs multi processor, read/write to memory, 32 vs 64 bit)
– Input
You might be little bit suprised by this, but hardware is not such a big deal. Input is the real problem here.
The bigger the input the more time it will take to finish.
